‘If we don't have consent, we need to have beneficence’: Requiring beneficence in nonconsensual neurocorrection

Abstract Neurointerventions—interventions that cause direct physical, chemical or biological effects on the brain—are sometimes administered to criminal offenders for the purpose of reducing their recidivism risk and promoting their rehabilitation more generally. Ethical debate on this practice (henceforth called ‘neurocorrection’) has focused on the issue of consent, with some authors defending a consent requirement in neurocorrection and others rejecting this. In this paper, I align with the view that consent might not always be necessary for permissible neurocorrective use, but introduce a qualification I argue ought to inform our ethical and legal analysis of neurocorrection if we are to administer neurocorrectives nonconsensually. I maintain our use of nonconsensual neurocorrection should be constrained by a beneficence requirement—that it should be limited to neurocorrectives that can be expected to benefit those required to undergo them; and my argument is that a beneficence requirement is necessary in order to safeguard against offender abuse. I highlight how we afford a heightened protective role to beneficence in other instances of biomedical intervention where consent is absent or in doubt; and I argue a beneficence requirement is also necessary in the correctional context because alternative candidate protections would provide insufficiently strong safeguards on their own. I then consider whether requiring beneficence in nonconsensual neurocorrection would (a) be incompatible with penal theory, (b) be objectionably paternalistic, or (c) foreclose many fruitful avenues of crime control. I argue in each case that it would not.

beneficence, consent, criminal rehabilitation, neurocorrectives, neurolaw, protections against abuse Neurointerventions-interventions that exert direct physical, chemical or biological effects upon the brain 1 -are sometimes deployed by the institutions of criminal justice for the purpose of reducing the recidivism risk posed by offenders or promoting their rehabilitation more generally. Two such 'neurocorrectives' are currently in use beyond the research phase in some jurisdictions. In the United Kingdom, for example, courts have the sentencing option of a Drug Rehabilitation Requirement, 2 wherein substance-abusing offenders are obliged to submit to opioid substitution therapy in order to curb their addiction and consequently facilitate their rehabilitation. And in some jurisdictions in the United States and Europe, sexual offenders can be required to undergo antilibidinal intervention (ALI) or 'chemical castration' either as part of their sentences or as a condition of parole or release. 3 These examples, however, may be just the beginning. There is reason to believe a much wider range of 'neurocorrectives' will become available as neuroscientific and pharmaceutical knowledge advances-for example, pharmaceutical and/or brain stimulation interventions to improve impulse control, enhance empathy or attenuate aggression. 4 Unsurprisingly, questions about whether and how we should deploy these interventions have been the subject of much scholarly debate.
This ethical debate has given rise to two broad positions with respect to the use of nonconsensual neurocorrection-that is neurocorrection administered without the valid (or free and informed) consent of offenders. This would be where, for instance, neurocorrection is mandated as part of an offender's sentence, or where coercive pressure is placed on offenders to submit to neurocorrection by making it a condition of their parole or early release. 5 On one side, some authors argue against nonconsensual neurocorrection on the grounds that it involves an unjustifiable infringement of offender rights (specifically the rights to bodily and/ or mental integrity), 6 and/or is objectionably disrespectful of offenders as rational and autonomous agents. 7 On the other side, it is argued the State sometimes has strong public protection reasons for administering neurocorrectives even when consent is absent, and the aforementioned rights and respect-based objections do not count against the use of nonconsensual neurocorrection across the board. Some authors argue, for example, that in committing crime, offenders render themselves liable to some sort of intrusive and/or defensive action on the part of the State, and that this could include liability to neurocorrection when such intervention is a necessary and proportionate response for the protection of the public. 8 Others argue that nonconsensual neurocorrection is not necessarily impermissibly disrespectful. 9 In this paper, I align with the latter camp in holding that a strong moral case can be made for the permissibility of nonconsensual neurocorrection when offenders would pose a serious risk to the public upon societal re-entry. However, I introduce a qualification I maintain ought to inform our ethical and legal analysis of nonconsensual neurocorrection. I argue that in deploying neurocorrectives nonconsensually we should be constrained by a beneficence requirement in order to safeguard against offender abuse. In other words, our use of nonconsensual neurocorrection should, for safeguarding reasons, be limited to neurocorrectives that can be expected to benefit those required to undergo them. Chew, C., Douglas, T., & Faber, N. S. (2018). Biological interventions for crime prevention.
In D. Birks & T. Douglas (Eds.), Treatment for crime (pp. 11-43). Oxford University Press. 5 There is disagreement in the literature as to whether neurocorrection imposed as a condition of parole or early release is inherently coercive and hence nonconsensual. For the sake of argument in this paper, I assume some such instances would be. beneficence are both necessary if we are to avoid violating offenders' human rights.
My argument here differs from both these stances in that it defends a beneficence requirement in nonconsensual neurocorrection on purely instrumental grounds. I am not contending offenders have a right that neurocorrectives be beneficial, nor am I claiming that rights-based considerations necessarily preclude their nonconsensual use. Instead, I argue against the use of even proportionately harmful nonconsensual neurocorrection on the grounds that, absent beneficence in nonconsensual treatment, we have insufficient protections against abuse. I believe this argument is important and timely because there is currently legal scope (in some jurisdictions) to administer hormonal treatments nonconsensually to sexual offenders for whom such treatment would not be beneficial. 15 This situation should, I contend, be remedied before the range of neurocorrectives at our disposal broadens.
My discussion is organized as follows. In Section 2, I outline my argument for a beneficence requirement. I highlight how we afford a heightened protective role to beneficence in other instances of biomedical intervention where consent is absent or in doubt. And I argue a beneficence requirement is also necessary in the correctional context if we are to ensure sufficiently strong protections against abuse.
Section 3 anticipates and addresses the following potential objections: that requiring beneficence in nonconsensual neurocorrection would (a) be incompatible with penal theory, (b) be objectionably paternalistic, and (c) foreclose potentially fruitful avenues of crime control. Section 4 concludes.
Some clarificatory comments before we proceed. This paper assumes throughout that the purpose of neurocorrectives is primarily rehabilitative.
I take it our principal reason for using neurointerventions in criminal justice is to facilitate dispositional changes in offenders in order to reduce crime and/or its social costs, and not to find new and additional ways of punishing these individuals. I assume further that the goal of crime reduction is primarily pursued for the benefit of society, while also acknowledging that rehabilitation through neurocorrection might sometimes be pursued solely for the benefit of offenders themselves (such as when, e.g. opioid-substitution therapy is made available to an offender who poses no great risk of future recidivism but for whom recovery from addiction would be beneficial). My concern in this paper, however, is with the former kinds of situations: to argue for a beneficence requirement in situations where crime prevention is the primary ground for intervention, and where neurocorrection is pursued in the absence of valid consent. I additionally assume that when it comes to nonconsensual neurocorrection, this intervention can also constitute punishment or part-punishment because of the liberty and autonomy restrictions necessarily intended and involved. And I argue briefly (in Section 3) that these punishments or part-punishments would be compatible with penal theory even if subject to a beneficence requirement.
I concede there may be other instrumental reasons for requiring beneficence in neurocorrection (aside from safeguarding) that I do not rely upon. Beneficial neurocorrectives might, for example, be more effective in facilitating rehabilitation and the reduction of recidivism than harmful ones. Nonbeneficial neurocorrection might also undermine both offenders' and the wider public's trust in healthcare and, in so doing, precipitate poorer healthcare outcomes.
But I do not utilize these points to support my argument for a beneficence requirement because we lack the necessary empirical evidence. It is plausible that some nonbeneficial interventions might render offenders less disposed to engage in crime even if it is also intuitively plausible that offenders with an improved level of wellbeing could be less likely to recidivate. And while it is credible that nonbeneficial neurocorrection would at least erode offenders' trust in healthcare professionals, the empirical fact of the matter in the case of both offenders and the wider public would still depend on whether the physicians involved are seen to relate to those who carry out standard clinical procedures. 16 In speaking of nonconsensual yet beneficial neurocorrectives, moreover, I am rejecting the thought that a state of affairs can only ever be good for a person if they desire and validly consent to it.
I assume a person can be harmed through nonconsensual treatment yet still receive overall benefit depending on the specifics of the treatment and situation. I am thus rejecting some desire-based accounts of well-being which hold that well-being consists solely in the satisfaction of one's informed desires.
Finally, I do not consider a requirement for beneficence in nonconsensual neurocorrection to be equivalent to a requirement of 'therapeutic necessity'. 17 Certainly, treatments that are necessary for managing recognized diseases or disorders typically benefit their recipients. 18 But not all candidate neurocorrectives target recognized diseases or disorders and it would be a mistake to think that this precludes the possibility of their being beneficial for a given recipient.
We can readily agree, for example, that treatment that serves to attenuate a person's impulsively aggressive behaviour (and that does not otherwise render them depressed, apathetic, debilitated or incompetent) plausibly benefits that individual insofar as it enhances their control over their emotions and behaviour in response to provocation. And we can agree upon this even if that individual does not meet the criteria for diagnosis of a recognized disorder of aggression. 19 Requiring beneficence in nonconsensual neurocorrective 15 The consensus is that paraphiliacs are the only subpopulation of sexual offenders for whom ALIs might be beneficial, see Fitzgerald, E. (1990) (2), 384-408, p. 394, for a discussion of the therapeutic necessity requirement in the case law of the European Court of Human Rights. 18 I say 'typically' because it is not clear that treatment that combats a particular disorder but that nonetheless has a plethora of unpleasant and/or debilitating side-effects is always beneficial for its recipient. use is thus not the same as requiring that neurocorrection be limited to the treatment of acknowledged diseases/disorders. Though, of course, in many instances, beneficial neurocorrection could be coextensive with such treatment.

| PROTECTING AGAINST OFFENDER ABUSE
It is uncontroversial to state that neurocorrectives, like all biomedical interventions, require protections against abuse. These interventions impact upon the most intimate spheres of human life (i.e. one's bodily and mental states); they are capable of exerting profound changes in those they target; and their targets are in a position of supreme vulnerability both because of the significance of the intervention's outcome for them, and because of the imbalance of power and control over the outcome that characterizes the doctor-patient relationship. The history of biomedicine, moreover, is replete with instances in which this capacity and power has been used abusively.
There are the numerous atrocities of Nazi medicine, 20 the infamous Tuskegee syphilis study (where participants unknowingly received placebos rather than treatment for syphilis), 21 and the notorious use of prefrontal lobotomies to treat socially undesirable behaviour, 22 to offer but a few examples.
This dark history, together with the fact of patient vulnerability, explains (at least on one narrative) why biomedicine has undergone a medical ethics revolution, investing itself with several legal and codified safeguards against abusive practice. 23 The work of practitioners and researchers is nowadays expected to be governed by four canonical principles, namely respect for patient autonomy, beneficence, nonmaleficence and justice. 24 The law, moreover, reflects these principles in making medical intervention in competent adults without informed consent a criminal offence (respect for autonomy); in deeming physicians liable to negligence claims (civil or criminal) if they breach their duty of care to their patients (beneficence and nonmaleficence); and in requiring that practitioners do not discriminate against patients in the delivery of care (justice). 25 The requirement for valid consent to medical investigations and treatment is arguably the key pillar of ethical biomedicine in contemporary practice. However, there are some very limited instances in which a consent requirement does not (and sometimes cannot) assume an overarching guiding role. A requirement for informed consent is not invoked in the case of individuals who lack the capacity to give informed consent for various reasons. 26 There are also some limited (controversial) instances where competent adults can be required to undergo clinical assessment or intervention in nonvoluntary circumstances, though in these instances they are still required to be fully informed.
Mental health law in several jurisdictions, for example, allows for the involuntary detention and treatment of mentally ill patients who pose a threat to themselves and/or others. 27 Public health law also sometimes permits that patients suffering from communicable diseases be detained against their will (and sometimes, controversially, be involuntarily treated). 28  There can, however, be negative consequences for offenders who do not participate or who fail to accept the terms of their parole or probation. This means it is not always required that offenders freely consent to intervention, even if a right to refuse treatment is normally upheld.
I maintain that when a requirement for valid consent to medical intervention is absent, the need to bolster alternative protections is paramount regardless of whether the intervention is for standard clinical, public health or correctional purposes. And if we are to include neurocorrection among the limited contexts in which involuntary medical intervention is (controversially) permitted, we must ensure that adequate and well-defined alternative protections govern its usage. I argue a beneficence requirement is an apt and necessary protection to adopt in this context-first because requiring beneficence would be consistent with our practices in other permitted instances of involuntary medical intervention, and second because alternative candidate protections are inadequate on their own. Let me elaborate. orders only expected to be used 'when there is reasonable evidence to suggest … there will be benefits to the individual'. 37 Public health legislation similarly only allows for mandatory vaccination against (or supervised treatment of) grave infectious disease threats when the safety profile of the proposed intervention is high and clear benefits are also to be obtained for the individual who submits to it. 38 My point here is that, given neurocorrection is similar to the above contexts insofar as it aims to manage chronic threats biomedically, requiring beneficence in its use would be consistent with existing protective practices in these other regimes. I thus affirm we have at least presumptive reason to favour a beneficence requirement in nonconsensual neurocorrection.
I imagine the reader at this point will be contemplating the obvious disanalogies between neurocorrection and healthcare, and querying whether safeguarding in the correctional context warrants a beneficence requirement. It might be pointed out that if neurocorrection is part of a sentence or a term of parole then it is inescapably tied up with penal theoretic considerations; and safeguarding against abuse when an intervention is serving at least some punitive function is not usually thought to necessitate beneficence. We protect against abuse elsewhere in the correctional context, after all, by requiring that any harms incurred are neither disproportionate to the offender's crime nor to the societal threat they pose. 39 We also often demand these harms be no more severe or restrictive than alternative, effective means of reducing the offender's recidivism risk.
Why not then rely on a proportionality requirement and/or a 'least In these minor cases, the proportionality requirement would likely be violated in any case if neurocorrectives were imposed. been shown to be particularly cautious, with mental health professionals and judges tending to overpredict future violence (both nonsexual and sexual). 42 And while the predictive accuracy for risk is reportedly much improved when clinical and actuarial methods of risk assessment are utilized in tandem (and by the latter, I mean the use of algorithmic risk assessment tools), 43 mere proportionality considerations might still not prevent our imposing more harm through neurocorrection than is necessary to reduce recidivism risk.
Consequently, I contend a mere proportionality requirement would provide insufficient protections against offender abuse. 44 What then, about a 'least harmful alternative' requirement?
Would requiring that neurocorrection be the least harmful (effective) means of reducing an offender's recidivism risk afford sufficient protections against abuse? Again, I argue no. Imagine, for instance, that an impulsively violent offender's risk could be reduced by a pharmaceutical that suppressed their violent impulses but which also rendered them apathetic. Suppose further that this is the only effective means of protecting the public from the offender's violent outbursts aside from continued incarceration-that conventional rehabilitative measures such as anger management training or cognitive behavioural therapy would be (or have proven to be) ineffective on their own. In this scenario, nonconsensual neurocorrection might be less harmful than the carceral alternative. It would restore the offender's freedom of movement, better facilitate the preservation of friendship and family ties, and release the offender from the grave physical and mental health threats that prevailing prison conditions often create (though it would still be expected to be at least mildly harmful overall). 45 Yet, I dispute that favourable comparisons with prevailing practice are anyway helpful in constructing adequate safeguards. This is because I hold, along with others, that current carceral practices are often unjustifiably harmful anyway. Prisoners are frequent victims of violent and/or sexual assault, often serve their sentences in overcrowded living environments, and regularly do not have their mental health issues and needs adequately accommodated for within the prison environs. 46 To rely on the requirement that neurocorrection be better than imprisonment does little to safeguard against its abusive deployment when prevailing practices themselves allow for abuse. And while it might be more humane to allow offenders to undergo neurocorrection rather than long(er) imprisonment in a given instance, in the absence of free and voluntary consent to the former we need stronger protections than that which a mere comparison with the carceral alternative affords. A 'least harmful alternative' requirement thus cannot adequately protect against abuse in neurocorrection if the alternatives involve incarceration as it is currently practiced.
The reader might still be unconvinced that the inadequacies of the abovementioned protective measures entail a beneficence requirement is necessary. They might respond that a requirement for mere nonmaleficence would suffice. Why, after all, would a neurocorrective have to produce benefits for its recipient when merely requiring that it 'do no harm' would also guard against its being used abusively? A beneficence requirement is, in the end, just overkill, so the response might go.
I agree that a nonmaleficence requirement in neurocorrection would offer protection against offender abuse. However, I contend a nonmaleficence requirement in nonconsensual neurocorrection amounts to the same as a beneficence one-that is, it also requires that intervention produce benefits for its target. This is because nonconsensual neurocorrection in-and-of-itself falls foul of nonmaleficence. Interfering in the affairs of another without their valid consent is itself a harm. Interfering with their body and/or mental states nonconsensually, moreover, is a particularly significant harm and one that is likely to be experienced as very intrusive and unpleasant. 47 As such, nonconsensual neurocorrection does not satisfy a requirement for nonmaleficence unless the effects of the intervention are sufficiently beneficial as to counteract the harm of nonconsensual treatment. And given that it is improbable that the harm of nonconsensual treatment and the beneficial effects of intervention will map onto each other exactly, ensuring that no harm is done requires that intervention produce net benefit. Nonmaleficence, in this context, therefore requires beneficence.
The reader might instead object, however, to the need to focus on benefits and harms at all when it comes to protecting against abuse in neurocorrection. They might suggest a requirement to respect human dignity would be an appropriate alternative protection and one to be preferred over an approach that involves making substantive judgements about what would be beneficial for others. understanding, neurocorrection in the absence of valid consent necessarily offends against human dignity. For others (including myself), there is still some scope to remain respectful of human dignity even when intervening in another person's affairs against their will. We can still respect offenders' rational and autonomous agency by working to protect and promote their capacity for independence and rational self-determination in matters apart from the mandatory or conditional terms of their sentences. We can also involve them in discussions pertaining to their neurocorrective treatment and take account of their views regarding some of the specifics of treatment (e.g. their views on which pharmaceutical to use when more than one option is available). 48 And we can refrain from deploying particularly invasive interventions nonconsensually (e.g. psychosurgery or direct brain stimulation), thus avoiding those methods that-due to their substantial infringement upon offenders' bodily integrity-would be invariably disrespectful in the absence of valid consent.
Yet, I still maintain we also need a requirement that references the harms and benefits of intervention if we are to have sufficient protections against abuse. Abuse, after all, is defined as behaviour that is unjustifiably harmful to another; and guarding against such behaviour requires that we mitigate the ease with which gratuitous harming can take place. It is not clear to me that a requirement to respect human dignity can achieve this goal alone-that it can provide adequate defences against abuse in isolation from a requirement that references the expected benefits and harms for the individual targeted. We could arguably remain respectful of human dignity when administering noninvasive neurocorrectives nonconsensually if we take appropriate steps to protect offenders' rational and autonomous agency. But this still does not preclude our imposing an unjustifiably harmful intervention, given that dignity-based considerations do not directly reference harms and benefits at all.
Avoiding unjustified harming through neurocorrection thus requires that we also address what level of harm to offenders we can safely permit. And given the abovementioned real-world difficulties in relying on an assessment of proportionate harm or in requiring that the 'least harmful' course of action be followed, I still contend a beneficence requirement is necessary to forestall the risk of abuse through neurocorrection.
A final difficulty that might be voiced at this juncture concerns the usefulness and adequacy of a beneficence requirement in the absence of a clear account of benefit or 'best interests'. The worry here is that, in the absence of clear guidance on what constitutes a benefit, a legal and codified requirement for beneficence will not adequately protect against abuse. 49 I agree. I accept that that we need a clear account of benefit if a beneficence requirement is to do the work I am expecting of it. However, I do not think this presents a problem for my argument as I believe such an account can be provided. And while I lack the space to develop such an account in this paper, a promising starting point would be to look at other spheres that are at least partially concerned with welfare promotion; to examine the substantive judgements that these spheres have made about how to improve people's well-being; and to extrapolate the guidance proffered to the neurocorrective context accordingly.
We thus might, for example, look to standard medical practice and public policy approaches to health and education, identify the kinds of things these spheres take to constitute a benefit to individuals, and then assess which of these benefits are also amenable to enhancement through neurocorrection in order produce a clear account with which to work. 50 This groundwork is a necessary prerequisite if a requirement for beneficence is to serve as an effective safeguard. But once such an account is in place I maintain a beneficence requirement will afford the required protections. Looking first to the objection that beneficial, nonconsensual neurocorrection would be incompatible with offender punishment, let me reiterate that I consider the primary purpose of neurocorrection to be rehabilitation, not punishment, but accept that when administered as part of a sentence or a condition of parole (and hence when involving some liberty/autonomy restriction) neurocorrection also serves some punitive purpose. The mere fact that such punishment can be expected to benefit its recipient, however, is not penologically problematic so long as the overall punishment dispensed remains proportionate and capable of furthering punishment's goals. 51 Additional punishment imposed alongside or prior to beneficial, nonconsensual neurocorrection, after all, could render the overall burdens meted out to be proportionate to the gravity of the offence, and sufficient for deterring crime and communicating censure. And even if the neurocorrective itself is to serve as the principle (or sole) sanction, this would I contend be consistent with penal theory so long as the harmful aspects of intervention (i.e. its nonconsensual administration and any harmful effects) are sufficient for advancing punishment's goals of retribution, deterrence or denunciation.

| SOME CHALLENGES CONSIDERED
Could proponents of canonical theories of punishment be content with merely pro tanto harmful punishment such as this?
That is, could they be satisfied with punitive measures that elicit some harms but also produce benefits that might ultimately prevail over these harmful features? I think so, though I cannot defend this claim thoroughly here. 52 Let me suggest, however, that even the retributivist might be satisfied with mere pro tanto harm so long as this harm remains proportionate to the offence and precedes the arrival of any benefits to offenders. Retributivists, after all, do not typically take temporally distant punishment outcomes into account when discussing issues of proportionality. They thus have 'very little to say' about what follows after punishment has been served. 53 What about the worry that nonconsensual, beneficial neurocorrection would be objectionably paternalistic? Admittedly, this concern might strike some as odd. Worries about paternalism are unlikely to be at the forefront of one's mind when one contemplates nonconsensual neurocorrection, given that these interventions can be intended as punishment and typically will (as is the case with medical interventions usually) be accompanied by some undesirable, unpleasant or inconvenient side-effects. 54 Yet, a critic might insist that nonconsensual yet beneficial neurocorrectives are vulnerable to the charge of paternalism because they (a) aim to further the offender's good irrespective of their own will; and (b) their deployment is motivated by the negative judgement that offenders lack the ability to (and hence will not) pursue their own good through beneficial neurocorrection unless the latter is mandated or incentivized. 55 In response, let me first state that it is not obvious that nonconsensual, beneficial neurocorrectives necessarily express negative judgements about offenders' prudential abilities. As already indicated, the principal reason for deploying neurocorrectives nonconsensually might be to ensure that that an offender's risk of recidivism is reduced; and as such, little thought might be given to whether the offender would freely choose intervention if it were not mandated or made a condition of parole.
Nevertheless, let us assume for the sake of argument that some instances of nonconsensual neurocorrection are motivated by this kind of negative judgement and that all necessarily intend to further offenders' own good irrespective of their own will. I still do not think that nonconsensual, beneficial neurocorrection is objectionable by virtue of its paternalism so long as the primary purpose of intervention is to prevent harm to others.
Here, I am allowing (in line with some views) that nonconsensual intervention meets the criteria for paternalism if the good of the recipient is but one reason for acting. 56 But I dispute that these mildly paternalistic acts are objectionably paternalistic if the key reason for intervention is the prevention of other-directed harms. In the presence of this primary goal, I believe any additional paternalistic intent need not enter into our calculations when it comes to assessments of permissibility. However, when benevolence toward the offender is the sole or primary motivator for acting, I concede there is reason to object to the paternalism involved and hold that further details would be needed to make judgements about overall permissibility in these cases.
Turning finally to the concern about foreclosing potentially effective avenues of crime control, I concede this is something we have to accept, but dispute that a beneficence requirement would unduly circumscribe the range of neurocorrectives that could permissibly be deployed nonconsensually. A beneficence requirement would mean we would be prohibited, at least in typical cases, from utilizing neurocorrectives that merely induce apathy in offenders, for example. Yet, this does not limit the prospects for utilizing neurocorrection as a public protection tool excessively. There are many candidate neurocorrectives that would plausibly benefit some subpopulations of offenders. Some offenders' lives might go significantly better for them if their impulse control could be improved through neurocorrection. Others' well-being might increase if neurocorrection could enhance their ability to establish and maintain close connections with others (if, e.g. aggressive tendencies or empathy deficits have hampered this). Requiring beneficence would certainly restrict the populations to whom various neurocorrectives could be administered nonconsensually. But it would not preclude their use entirely, and such restriction is, I believe, a price worth paying if we are to have sufficient safeguards against abuse.

| CONCLUSION
To sum up, this paper has made a case for requiring beneficence in nonconsensual neurocorrection. I first highlighted how a beneficence requirement is afforded a heightened protective role in other situations where consent to biomedical intervention is absent or in doubt. I then 51 I acknowledge that were one to accept a pure rehabilitation or moral education theory of punishment, then the expectation of offender benefit would not be problematic as these theories consider the benefitting of offenders to be a legitimate aim of punishment (sometimes even its justifying aim, see Hampton, J. (1984). The moral education theory of punishment. Philosophy and Public Affairs, 13(3), 208-238). However, given that these theories are no longer dominant nor popular within legal philosophy, the question at issue here is whether beneficial neurocorrection would prevent the realization of the (commonly argued that a beneficence requirement is necessary to safeguard against abuse in nonconsensual neurocorrection because it affords stronger protection than alternative requirements would in its absence. I finally addressed three potential objections to my line of argument.
I concede we would have greater protections against abuse if neurocorrectives were also subject to a consent requirement.
However, I think there are some circumstances in which tolerating some risk of misuse would be preferable to avoiding neurocorrection altogether. In the case of those who have committed the most serious of offences, requiring neurocorrection prior to societal reintegration would be preferable to risking release sans intervention, despite the risk of misuse. My argument here is that if we are to risk misuse by relinquishing a requirement for consent, we must construct adequate alternative protections. And a beneficence requirement is one necessary foundation for such a structure.
